what i didn't understand is how some can say Superman dosen't kill but how else would it end? Zod is a Superman too so the police/amy can't do any thing to him. There is no jail on earth that can hold he, the phantom zone is gone. So if Superman flys away with Zod and continue fighting than what? Zod will still kill because thats Superman's only weakness in the movie so far. So he HAD to do it to save everyone.
